South Florida COVID-19 Trajectory

Introduction

This is a special issue of the Miami Covid Project Trajectory Report including Palm Beach and Broward Counties. This report will be updated at the authors’ convenience.

Public understanding of science is critical in times of crisis. The following analysis was conducted to examine the trajectory of COVID-19 in the South Florida counties of Miami-Dade, Broward, and Palm Beach. For phased reopening, the White House has set guidelines for local municipalities in their “Opening Up American Again” report. In the report, it is highly suggested that:

1. Local areas show a downward trajectory in the number of positive cases as a percent of total tests over a two-week period, and
2. Local hospitals have capacity to handle all patients without crisis care.

The analysis begins by looking at the number of new positive cases each day and the number of total tests performed each day. The figures are presented together because as there is more testing, there are likely to be more positive test results. Therefore, the proportion of positive cases is also calculated. Given a flat or increasing number of tests performed, the proportion of positive cases is the key metric to be used when looking at epidemic trajectory. It is recommended that this proportion not exceed 5%.

Finally, to ensure hospitals can meet demand without crisis care, the COVID-19 positive hospitalization census, COVID-19 positive ICU census, and COVID-19 positive ventilation census is plotted over time. Census refers to the number of COVID-19 positive patients in the hospital, ICU, and on ventilators, respectively, on a given day.

For Miami-Dade, Broward, and Palm Beach Counties, this document shows the

• Full testing counts data,
• Count of positive and total COVID-19 tests since mid-March,
• Proportion of positive counts to total counts within the last two weeks,
• Proportion of positive counts to total counts since mid-March,
• Full COVID-19 hospitalization census data, and
• Counts of patients hospitalized with COVID-19 since the beginning of April

Total COVID-19 Tests by Day

The average number of COVID-19 tests performed each day has doubled from about 2,000 in early April to over 10,000 in July. Over the past two weeks, there has been an average increase of 276 new additional tests performed each day in Miami-Dade County. This data is presented on a log scale.

Positive COVID-19 Tests by Day

There was a general decrease in the number of new positive test results from early April until around mid May when Miami-Dade reopened. Afterwards, this trend flattened out and then increased. Over the past two weeks, there has been an average increase of 36 new additional positive cases each day, per day in Miami-Dade County.

A record high of 3561 for new positive cases was obtained on July 11th.

Proportion of Positive Cases within Past Two Weeks

During the 14-day period from 06 July to 20 July, there was a decrease in the proportion of positive COVID-19 cases reported in Miami-Dade County. Over this period, there was an average increase of -0.21 percentage points per day for new positive cases. However, over the past week, this proportion may be decreasing. Given a flat or increasing number of tests performed, the proportion of positive tests obtained is the key metric for examining COVID-19 trajectory. The percentage of positive test results obtained has exceeded the 5% positive threshold recommended by the World Health Organization (WHO) for reopening.

Proportion of Positive COVID-19 Tests by Day

Overall, the proportion of positive test results out of all tests decreased significantly from just under 20% in early April to the proportion of about 5% at the end of May. This is function of test availability and the population being tested. Overall, since the county reopened, the proportion of positive tests is now increasing significantly over time, returning to the current average of over 20%. Given a flat or increasing number of tests performed, an increase in the proportion of positive tests obtained points to evidence of increased COVID-19 community spread in Miami-Dade county.

COVID-19 Hospitalization Data

Full Data

The data below is COVID-19 hospital census data for Miami-Dade County for all dates with available data since April 2.These columns are: the number of patients hospitalized with COVID-19 (Hospitalized), the number of patients in intensive care with COVID-19 (ICU), the number of patients in intensive care with COVID-19 who are also on ventilators (Ventilated), the number of patients positive for COVID-19 that were admitted the previous day (AdmitPrevDay), the number of patients recovered from COVID-19 that were discharged the previous day (DischPrevDay), and the net admission of patients positive for COVID-19 the previous day (DeltaAdmit; a negative value means more recovered patients were discharged than sick patients admitted).

Hospital COVID-19 Census Trajectory

We now show a census plot of hospitalizations, patients in ICU, and those in ICU on ventilators (shown on a log scale) for Miami-Dade County. Overall, since mid-April, the number of COVID-19 positive patients in Miami-Dade County hospitals remained constant at around 700 people in hospitals until early June. The COVID-19 ICU census decreased from its reported peak of 285 on April 17th to around 100 as of June 6th. Overall, the number of COVID-19 patients on ventilators has decreased from its highest point of 192 ventilated on April 22nd to around 60 on June 6th. However, the observed decreasing trends for ICU census and ventilation census have reversed over the past five weeks and begun to increase for ICU census and ventilation census, respectively. Additionally, county hospitalizations have begun to increase as well.

On July 21st, 2299 COVID-positive patients were hospitalized, a new high during the period analyzed. Additionally, on July 21st, 527 COVID-positive patients were in the ICU, the most recorded during the epidemic. Finally, on July 21st, Miami-Dade hit a record high for ventilations with 312 COVID-positive patients. This number may increase as ventilation tends to lag behind ICU admission. Furthermore, there has been a rise in deaths reported per day for Miami-Dade County over the past two weeks.

We also show the proportion of patients hospitalized who are in the ICU and the proportion of those patients in the ICU who are ventilated.

Overall, the percentage of COVID-19 hospitalized patients requiring intensive care has decreased from over 40% in early April to around 13% in mid May. In the past five weeks, this trend has reversed and the percentage of hospitalized patients in the ICU has begun to increase to approximately 25%. Additionally, the percentage of patients in the ICU on ventilation has decreased from approximately 85% in early April to the current percentage of approximately 50%. Over the past week, this decrease has flattened.

COVID-19 Deaths by Day

Overall from March 16th to approximately May 25th in Miami-Dade County, there was a decrease in the number of deaths per day. The orange triangle depicts the county reopening date. The peak number of deaths so far reported was 30 on April 27th. This decrease in deaths may be attributable to advances in COVID-19 treatments and standard of care. A decrease in median age of those impacted could also partially explain this decrease. However, over the past two weeks, there has been a slight increase in the number of deaths reported per day in Miami-Dade County.

Note: Due to delays in classifying the cause of death and thus of reporting deaths due to COVID-19, the most recent data will undercount the number of deaths. For this reason, the last two weeks were excluded from this analysis of deaths.

Hospital COVID-19 Census Trajectory

We now show a census plot of hospitalizations, patients in ICU, and those in ICU on ventilators (shown on a log scale) for Broward County. Overall, in Broward County, hospitalizations and ICU census trended downwards until approximately the first week of June. Subsequently, these trends reversed and now trend upwards. The trend for ventilation has increased over approximately the past two weeks. The COVID-19 ICU census had decreased from its reported peak of 152 on April 12th to a minimum of 41 on May 16th; currently, it has increased back to 269. The observed decreasing trends for ICU census has reversed over the past month and began to increase.Overall, the number of COVID-19 patients in ICU on ventilators decreased significantly from its highest point of 121 ventilated on April 12th to a minimum of 23 on May 13th; currently, there are 191 patients on ventilators in ICU. Additionally, county hospitalizations have begun to increase over the past five weeks.

On July 21st, 1319 COVID-positive patients were hospitalized. On July 21st, 269 were in the ICU. These are both record highs for the epidemic in Broward County. The 198 COVID-positive patients ventilated on July 19th was also a record high for Broward County.

We also show the proportion of patients hospitalized who are in the ICU and the proportion of those patients in the ICU who are ventilated.

Overall, the percentage of COVID-19 hospitalized patients needing intensive care has decreased from over 35% in early April, to the current rate of below 25%. In addition, the percentage of COVID-19 ICU patients requiring ventilation decreased from over approximately 85% in early April, to under 60% in June. However, over the past two weeks, this has again began to increase. This trend has reversed and begun to increase over the past week.

COVID-19 Deaths by Day

In Broward County, death rose until mid April before decreasing until approximately May 18th, the day the county opened (depicted by orange triangle). Over the past two weeks, there has been an increase in deaths for Broward County.

Note: Due to delays in classifying the cause of death and thus of reporting deaths due to COVID-19, the most recent data will undercount the number of deaths. For this reason, the last two weeks were excluded from this analysis of deaths.

Hospital COVID-19 Census Trajectory

We now show a census plot of hospitalizations, patients in ICU, and those in ICU on ventilators (shown on a log scale) for Palm Beach County. Overall, in Palm Beach County, trends for hospitalization census, ICU census and ventilation census decreased from April to mid May before reversing. Subsequently, we see an increase in hospitalization census, ICU census, and ventilation census for Palm Beach County. The COVID-19 ICU census has decreased from its reported April peak of 103 on April 12th to 55 on May 23rd; currently there are 141 COVID-19 patients in ICU, an all time high. Overall, the number of COVID-19 patients on ventilators has decreased significantly from its highest point of 75 ventilated on April 4th to to 33 on May 18th; currently there are 82 COVID-19 patients in ICU who are on ventilators. The observed flat trends for hospitalization, ICU, and ventilated census have reversed over the past month and are increasing.

On July 16th, 689 COVID-positive patients were hospitalized. On July 14th, 151 were in the ICU and 90 were on ventilators. This past week, Palm Beach County experienced record highs for the number of COVID-positive patients hospitalized, in the ICU and on ventilators.

We also show the proportion of patients hospitalized who are in the ICU and the proportion of those in the ICU who are ventilated.

Overall, the percentage of COVID-19 hospitalized patients requiring intensive care has decreased from approximately 50% in early April to the current rate of approximately 20%. Additionally, the percentage of patients in the ICU on ventilation has decreased from 80% in early April to the current percentage of approximately 60%.

COVID-19 Deaths by Day

In Palm Beach County, COVID-positive deaths rose until mid April and afterward have been decreasing. This decrease in deaths may be attributable to advances in COVID-19 treatments and standard of care. A decrease in median age of those impacted could also partially explain this decrease. Over the past two weeks, deaths per day have been stable for Palm Beach County.

Note: Due to delays in classifying the cause of death and thus of reporting deaths due to COVID-19, the most recent data will undercount the number of deaths. For this reason, the last two weeks were excluded from this analysis of deaths.

Conclusion

During the past two weeks, the number of positive COVID-19 tests has increased by an average of 36, 20, and 9 each day for Miami-Dade, Broward, and Palm Beach Counties, respectively. Additionally, there has been a substantial increase in the proportion of positive COVID-19 tests obtained within the past two weeks. Furthermore, hospitalization census, ICU census, and ventilation census for Miami-Dade County have all begun to increase over approximately the last fou weeks.

This past week, Miami-Dade County obtained record highs for cases, hospitalizations and the number of COVID-19 positive patients in the ICU and on ventilators.On July 21st, 2299 COVID-positive patients were hospitalized, a new high during the period analyzed. Additionally, on July 21st, 527 COVID-positive patients were in the ICU, the most recorded during the epidemic. Finally, on July 21st, Miami-Dade hit a record high for ventilations with 312 COVID-positive patients. This number may increase as ventilation tends to lag behind ICU admission. Furthermore, there has been a rise in deaths reported per day for Miami-Dade County over the past two weeks.Taken together, this evidence points to increased community spread of COVID-19 in Miami-Dade County and represents a significant concern for the area and for area hospital capacity.

For Broward County, the number of people in the hospital and in intensive care units have increased since the beginning of June; the number of people on ventilation has begun to increase as well. On July 21st, 1319 COVID-positive patients were hospitalized. On July 21st, 269 were in the ICU. These are both record highs for the epidemic in Broward County. The 198 COVID-positive patients ventilated on July 19th was also a record high for Broward County.

Finally, for Palm Beach County, hospitalization census, ICU census and ventilation census have all increased consistently since approximately mid May. On July 16th, 689 COVID-positive patients were hospitalized. On July 14th, 151 were in the ICU and 90 were on ventilators. This past week, Palm Beach County experienced record highs for the number of COVID-positive patients hospitalized, in the ICU and on ventilators.

In summary, for all counties analyzed, there have been record highs obtained for COVID-19 patients in hospitals and in the ICU. Additionally, all counties experienced record highs for cases during the previous the previous two week period. This represents a major concern for area hospital capacity. Aggressive countermeasures should be taken immediately to arrest these increases and ensure hospitals have sufficiently capacity.
